ISO7741: Isolation supply different in both supplies

Raj Narnoli

Part Number: ISO7741

Will the IC work accurately if Vcc1 is 5V and Vcc2 is 3.3?

Hi Raj,

Thank you posting to E2E! Please normally anticipate responses during business hours.

Yes, TI’s digital isolators, including ISO7741, will operate normally and accurate to the datasheet if Vcc1 = 5V and Vcc2 = 3.3V or vice versa.

Note that input signals should match the corresponding Vcc level and the output signals will match the corresponding Vcc as well.

Best,

Manuel Chavez
